tion of the head I2.

through slot 230/, into recess 33. Upon releasing the lever 8, a spring moves the rod 31 into the clamping position which is shown in Fig. 8, in which insert 381:. clamps the tip of the unreversed necktie form N.

A collar 3 is fixed to the hollow standard 2 by means of a pin 4. This collar 3 supports an annular bracket 5, which is provided with a horizontal stop-arm 8. Another collar 9 is slidably mounted upon said hollow standard 2. A helical compression spring 9a biases the collar 9 to the normal top position which is shown in Fig. 1. This movable collar 9 is integral with a rigid arm I0, which is fixed by means of a bolt to a vertically movable head I2. As shown in Fig. 4, said bolt II has a head Ila. Another collar I4, which has a head I5, is also slidable upon the standard 2. Said collar I4 is integral with a rigid arm I3, which is fixed to said head l2 by means of the bolt H, which is identical with bolt II. A disc l8 is fixed to the top of the standard 2. A helical shock-absorbing spring I9 has its upper end fixed to said disc I8.

Referring particularly to Fig. 4, the head I2 comprises a front plate 24. Said front plate 24 is made of metal or any other suitable rigid material. It is provided with end-flanges 25. Said end-flanges 25 are'integral with respectiveforwardly-inclined walls 26 which are inclined to each other, and said respective walls 28 are joined by an intermediate integral flange 21.

Said head I2 also includes a rigid rear plate 28, which is made of metal or other suitable material. A rear liner 29, which is made of resilient sponge rubber or other soft and resilient material,

abuts the inner face of the rear plate 28. A front liner 39, which is also made of sponge rubber or any other suitable soft and resilient material, has end-portions which abut the inner faces A rear metal leaf 3| is pivotally connected at 32 to the respective metal wall 26, so that said metal leaf 3| is turnable about a vertical axis. The free edge-wall of said metal leaf 3| is designated by the reference numeral 33 in Fig. 4. A second and front metal leaf 34 is pivotally connected at 35 to the respectivemetal wall 26, so that said leaf 34 is turnable about a vertical axis. The free edge-wall of .said front metal leaf 34 is designated by the reference numeral 38 in Fig. 4. I

Each of these metal leaves 3| and 34 is preferably, but not necessarily, of the full height of .walls of the enlarged forked head of the arm I9,

in order to clamp the plate 28 and the vertical edge-portions ofthe liners 29 and 39 and the Companion bolts I Ic are provided atthe'other vertical edge-porthus rigidly assemble the parts of head I2, and

.bolts II and I1 rigidly connect the head l2 to the identical arms I and I8.

The head I2 is provided with a clamping follower 38, which is provided with a top flange 39. This follower 38 consists of a vertical planar sheet of metal or other suitable material, which is provided with a resilient top bend 43 and with a resilient bottom bend 4|.

As showninFigs. 1-3, the median wall-portion The bolts. H, I! and H 21 of the front plate 24 is provided with superposed openings or cut-outs 42 and 43.

When the follower 38 is in the clamping position shown in Fig. 3, the top bend 49 of said follower 33 is located above the top opening 42, and the bottom bend 4| of said follower is located above the bottom opening 43. As further shown in Fig. 3, said follower 38 has a bottom flange 44. When the head I2 is in its bottom position which is illustrated in Fig. 2, i said bottom flange 44 abuts the stop-arm 8 of the fixed bracket 5. When the follower 3B is in said clamping position of Fig. 3 and Fig. 5, said follower 38 holds the leaves 34 and 3| in the clamping position shown in Fig. 5, in which the liners 29 and 39 clamp that portion of the necktie form which is located above the bottom end 3la of the reversing mandrel 23, against said mandrel 23.

A top stop-arm 46 is fixed to a collar 41, which is fixed by a clamping screw or the like to the horizontal tube 2|.

When the head I2 is in the top release or nonclamping position which is shown inFig. 1, the top flange 39 of the follower 38 abuts the stoparm 46. The resilient bends 49 and 4| of the follower 38 are then aligned respectively with the openings 42 and43, and said bends 40 and 4| then project through the respective openings 42' and 43. This releases the pressure on the leaves 34 and 3|, and on the liners 29 and 39, as shown in Fig. 4.

Fig. 4 also shows how the bottom bend 4| extends outwardly through the respective opening 43,3i8n the non-clamping position of the follow er The method of operation of the first embodiment is as follows:

While the head I2 is in its top position which is illustrated in Fig. 1, the operator presses on the pedal la, thus depressing the pedal 6 and moving the rod 37 upwardly relative to the fixed pipe 23, until the recess 38 of the rod 31 is horizontally aligned with the slot 23a of the tube 23. The operator then inserts one tip of the unreversed necktie form through the slot 23a into the recess 38. The operator then releases the pedal 1a, so that a suitable spring actuates the treadle or lever 6, so as to move the rod 31 into the clampingposition which is shown in Fig. 8, in which one tip of the unreversed necktie form N is clamped by the resilient insert 38a. As shown in Fig. 6, a part of the reversing mandrel 23 then extends into the upper end-part of the unreversed necktie form N. The length of the mandrel 23, from its slot 23a. to its bottom end 31a, is about 25% of the total length of the unreversed necktie form N, but this can be varied as desired, and it may be only a small fraction of the total length of the unreversed form. I have not shown a lining which is ordinarily stitched to the unreversed necktie form, and which is at the outer wall of said unreversed form, as this is conventional. V

The operator then moves the head |2 from'the top position which is shown in Fig. 1, to the bottom position which is shown in Fig. 12, while the tip of the unreversed necktie form N remains firmly clamped by said clamping insert 38a, and while the unreversed necktie form N extends vertically below the bottom end 31a of the reversing mandrel 23.

As shown in Fig. 3, when the head I2 is in its bottom position, the resilient liners 29 and 3|] extend above the top end of the unreversed necktie form N, and a part of the unreversed necktie v A I t of the necktiefforin N 'wh c extends; below'ithe infers 2'9 and an, sue t the tot-e1 1en gt eftrl 'neekt efermrebut can bevaried as desired, Likewise, in'tlie t"- om pos tions of the "liners 29 and at. their bet- 1;

' is reversed and the reversed part of said form fisffnoved upwardlyhpon the mandrel 23. Fig.8 showshow a part of the form N has been reversed. During the upward movement" of head l2, the unreversed part of the necktie is slid relaitive tofand in contact with the reversed part of the necktie iorm N. It will be noted that just as t head I2 is moved. to its bottomposition, the stop i l of the follower [38 strikes the stop-arm'S, thus producing a relativernovement between the follower 38 and the head i2, so as to movethe bends 40 and 4| out of their respective openings and '43, and thus clamping the upper end-part "of the unreversed necktie form N against the outer wall of the tube 23.

tion, the stop 39 abutsit he. stop 46;;so that the ,head 12 is moved upwardly relative to its iollower aga'nd the bends, 4t and 4 ar thus extended through the respective openings 42 and 43, thus releasing the clamping action of the rubber liners "29 and upon the necktie form N. When the head [2 has been thus moved back to its top position, either a part of or the entire necktie form has been reversed, depending upon the height of "the-mandrel" 23' above theslot 23a and said partially o r wholly reversed necktie form Nis located on the mandrel 23, wholly above the slot23a. I

Theoperatorthenpresses upon the pedal la, so as T to release the I bottom tip or bottom endportion'oi the necktie'form N from the reversing mandrel 33. The partially or fully reversed'necktie form can then be easily slid downwardly off the pipe 23 while the head l2 remains in its top position, If the necktie form is only partially reversed by the machine, said reversal can be "easily completed by hand. I prefer to reverseat i ast, 50%of the length of the form'N on the machine.

; In' the second embodiment which is shown in Figs.'912 inclusive, the resilient rubber liners 29 "and 30 are replaced by a pair of reversing rolls which have resilient outer layers 58 and 5 of "sponge rubber or other 'soft'and resilient material. fThese' rolls are provided with respective this 'ehds, whichare at the same level 'imay ex. dbel'ow or above the end 3141, 'or substantially part of unreversed ne'ck- Fare-provide 1n there-a al "and ir nzi a r d"*ti ai irfame'has' a rigid bottom legMa whichisintegifal w h a 1 3? 57fwhi9h'i fix dg h stafid m 2 by means of a 'clampihgscr'ew or the like; Said Jfranre is also integralwith a top leg 59,1 integral with a .collartfl which is fixed by "a clamping screw 6| or the likato the standard 2. Anyof'the collars previously mentioned can be made in two or more partswhichcan bfe suit "ably connected to each other in orderto' afiixthe sarne more readily to the standard *2.

Said bearing-block- M has a collar 62 a, which 'is fguide d steamy-err the standard 2. The standard 2 "fitssnuglydn thfe bore of said collar 62a, and said collar BZQa'is of substantial height, so that the shafts 52 and 53 are maintained horizontal and parallel and the gears G are maintainedin mesh with the racks 5'4 and 55, during the vertical movement of *bearing-block 62. e

The shaft 53 is provided with an extension, on which a collar63 is turnably'mounted. Sal'dX- tension of shaft 53 has a threaded end,,upon which a nut 66 is removablyfixed. A spacing cellar 65is'provided in order to permitthe collar 63 to turn freely relativetosaidextensionof the shaft 51a. Said collar 63 is provided with a. ha nd-hold'fi la. I I

The second embodiment is used as follows:

One tip of the unreversed form. N iscIaInpe'di to be held in the slot' 23a of the reversingmam- "drel 23 asin using the previous-embodiments This is done while the collar 62a is in its top po- 'sition. The unreversed'necktie form N then'ex tends in any desired proportionbelow thejbottom.

The operator then pulls downon hand-hold 64a, thus moving the fbearing-block 62 to its "position which is shown in Fig. 9, or below said position. HoweverQthe layersifl and' 'l are'preferablyalways maintained at aheight inwhich they are compressed at least partially by mandrel 23, so that said resilient layers and 5! always remain deformed in the shape which is shown in Fig. 12, out of normal cylindrical shapel The gears G and the racks 54 and turnthe reversing rolls in respective oppositedirections during this downward movement of the bearing-block 6 2 andof the shaftsBZ and 53. The reversing rolls, exert a downwardpull upon the upperpart 'ofthe uh'rev'ersedhecktie form, which is located above the end 31a. during said downwardm'ovefment of bearingblock 62,, when saidrolls contact with the original or unreversed necktieform above the end 371;. and below'the slot 23a. .The pull of the 1 reversing rolls is less than the "elam'ping force which holds theitip or end-portion of the unreversed form, so that'said vunreversed form N remains clamped to the reversing mandrel 23. I J I t I The operator then releases the hand-hold 54h, so that spring 912 can move the bearingebloekfl Ito its top position. During 'said upwardfmovemerit; the respective'directions' sen r0118 are turned. are shown by the respective curved arrows in Fig. 12, which also shows how the soft resilient the mandrel 23 and the necktie form N. These layers 50 and 5| are deformed partially or wholly layers 50 and 5| are deformed around around the mandrel 23, similar to the deforrnadesired part thereof.

In both embodiments, the length of the reversing mandrel 23, above the top of its slot 23a, may exceed the length of the necktie form, or be equal to or less than said length.

In each embodiment, the unreversed form N is reversed by the pressure of resilient means which exerts an upward sliding and reversing force upon the necktie form, beginning below the clamped top end of the necktie form. Said sliding. and reversing force presses the unreversed necktie form against an internal reversing mandrel.

When the device of the first embodiment is in the bottom clamping position which is shown in Fig. 3, the resilient liners 29 and 30 may extend horizontally wholly around the portion of the unreversed necktie form which is located above the bottom 31a of the reversing mandrel 23, so that said liners 29 and 39 make full horizontal contact with said part of the unreversed necktie form N, wholly around the circumference of the mandrel 23. If desired, and as shown in Fig. 5, said liners 29 and 30 may make only partial horizontal contact with that part of the unreversed necktie form N which is located above said bottom end 31a. Below said end 310., said liners 29 and 30 may press against the portion of the necktie form which extends below said bottom end 31a, in order to flatten said depending part of the necktie form N from its normal and substantially cylindrical shape. Indeed, the liners 29 and 39 may press the necktie form below said end 31a, into substantially flat shape, with the same effect as though said necktie form were placed upon a horizontal table upon which said necktie form was pressed by means of an iron or the like.

The unreversed or original necktie form is of the conventional type, in which the longitudinal edges of said form have been connected by stitches. I have described the reversal of an original necktie form which does not have ajlining strip. However, the invention is applicable to reversing all types of original necktie forms, including those which have one or more lining strips.

It is preferred to have a portion 'of the necktie form depending below the bottom end of the reversing mandrel, before starting the reversing operation. However, the invention is not limited to this feature, because the length of the mandrel above and below the point of clamping is optional.

The invention is not limited to the vertical position of the mandrel 23, although this is highly preferable. For convenience, and in order to avoid limiting the invention to said vertical position of the reversing mandrel, the bottom'end 31a of said mandrel 23 is designated as the outer end of said mandrel.

In each of the embodiments disclosed herein, there are movable reversing means which are longitudinally movable to an operative position in a longitudinal direction from the upper or inner end of the reversing mandrel towards the ram outer or lower end thereof. Said movablemeans are ,alsolreversely longitudinally movable in a form-reversing stroke, from said outer end of the reversing mandrel to said inner end. Said movable reversing means have auxiliary clamping means, namely, the liners 29 and 30 of the first embodiment, and the covering layers 50 and 5! of the second embodiment, which are located laterally outwardly of the slot 23a of the clamping. means which clamp a tip or end-portion of the unreversed form, in the operative position of said movable reversing means. In the first embodiment, said operative or starting position is the bottom position shown in Fig. 2. In the second embodiment, said starting position is shown in Fig. 9. During the reversing or operative movement of said movable reversing means, said auxiliary clamping means clamp at least a part of the necktie form which is located above or longitudinally inwardly of the outer end of the reversing mandrel, against the reversing mandrel. During said reversing movement, said auxiliary clamping means also hold that part of the necktie form which is located above or inwardly of the outer end or bottom end of the reversing mandrel, relative to said reversing mandrel. In each embodiment, the auxiliary clamping means preferably, but not necessarily, release the necktie form at the completion of the reversing movement. In this second embodiment, this is accomplished by making the mandrel 23 of sufiicient height, so that the reversing rolls ride upwardly off the reversed necktie form at the completion of the reversing movement.

The second embodiment makes it possible to use a machine of less height than in the first embodiment. Referring to Fig. 3, which shows the starting position of the head 12 in the first embodiment, this figure shows the full height of the unreversed necktie form N. It is clear that the height of the head l2, and of its liners 29 and .30, is less than the full height of the unreversed necktie form N. If it is desired fully to reverse the necktie form in the machine of the first embodiment, the bottom ends of the liners 29 and 3|] than the height of the liners 29 and 3|] of the firstembodiment, it is possible to design a machine according to the second embodiment, with a smaller height than in the first embodiment. In

each embodiment, as the unreversed necktie form is successively reversed, the reversed portion of the necktie form or the top part of the reversed portion of the necktie form is pressed against the reversing mandrel above the primary clamping means which include the slot 23a. In the first embodiment, the clamping liners 29 and 39 are located above and below the slot 23a, at the beginning of the reversing movement. In the second embodiment, the layers 50 and. 5| may be of sufiiciently small diameter so that said layers 59 and 5| are located wholly between the slot 23a and the bottom end 31a, at the beginning of the reversing movement. However, since the mandrel 23 preferably fits snugly in the interior of the unreversed necktie form, this does not interfere with the proper reversal of the form.

At the beginning of the reversing operation,

the part of the unreversed necktie form which is located below the clamping member 38a is reversed and slid upwardly on the reversing mandrel, thus forming an inner reversed cylin-i drical layer. The top of the unreversed part of the ecktie form forms an outer cylinder layer which is pressed against said inner layer and against the reversing mandrel. For practical purposes, the unreversed part of the form is pressed against the mandrel. As the reversing operation is continued, the outer unreversed layer of the necktie form is slid upwardly relative to the inner reversed layer, whose bottom remains clamped by the member 38a. As the reversing operation is continued, the bottom of the outer unreversed layer will be located above the member 38a, until finally the entire necktie form, in reversed condition, will be located on the reversing mandrel 23, above the clamping member 38a. The reversing operation can be stopped while a part of the necktie form remains unreversed. The necktie form can then be re-' moved from the mandrel, and the reversal can easily be completed by hand.

The reversing mandrel may be cylindrical or have any other desired shape.

I have described preferred embodiments of my invention, but it is clear that numerous changes and omissions can be made without departing from its spirit.
